For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
The method of the rate adapted that the embodiment of the invention provides specifically comprises: receive the multiplexed signals that comes from ply-yarn drill, a plurality of headers in this multiplexed signals carry multiplexing sequence identification; According to this multiplexing sequence identification, this multiplexed signals is gone here and there and be converted to parallel data in the mode of displacement; Then this parallel data is exchanged respectively and exports.
Referring to Fig. 2, the embodiment of the invention provides a kind of method of rate adapted, specifically comprises:
Step 101: ply-yarn drill carries out multiplexing to a plurality of cells to be sent, as interleaves multiplexingly etc., obtains multiplexed signals, owing to all comprise a header in each cell to be sent, then comprises a plurality of headers in the multiplexed signals.Low speed signal be through obtaining high speed signal after multiplexing, carries out multiplexingly as the low speed signal to 4 3.125Gb/s, obtains the high speed multiplexed signal of a 12.5Gb/s.
Step 102: ply-yarn drill adds multiplexing sequence identification for a plurality of headers in the multiplexed signals that obtains according to multiplexing order.
Wherein, adding multiplexing sequence identification can be specially: a plurality of headers are arranged to different values respectively, then according to wherein multiplexing order just can be discerned in the value and the position thereof of any header; Perhaps a plurality of headers are arranged to identical value, then the value according to described a plurality of headers can identify multiplexing order.For example, referring to Fig. 3,4 cells to be sent are arranged, length is N byte, and header is H, these 4 cells are carried out byte intertexture division multiplexing after, obtain multiplexed signals, then comprise 4 identical headers in the multiplexed signals, use H in the drawings respectively
1, H
2, H
3And H
4Expression is set to 1,2,3 and 4 according to multiplexing order respectively with their value, perhaps is set to A, B, C and D or the like, is used for identifying the multiplexing order of 4 headers; Also their value can be arranged to identical value in addition, as be 3, then represent multiplexing order for 4 continuous 3.
Step 103: power board receives the multiplexed signals that ply-yarn drill is sent.
Step 104: power board is according to the multiplexing sequence identification that prestores, the multiplexed signals of receiving is gone here and there and be converted to position parallel data accurately in the mode of displacement, the multiplexing sequence identification of a plurality of headers is not all not simultaneously in multiplexed signals, position parallel data accurately is meant any header in a plurality of headers that comprise in the parallel data in the multiplexed signals, and the position of this header in parallel data is identical with the position of this header in these a plurality of headers; The multiplexing sequence identification homogeneous phase while of a plurality of headers in multiplexed signals, position parallel data accurately is meant that parallel data is identical with described a plurality of headers.The multiplexing sequence identification that prestores is the multiplexing sequence identification that ply-yarn drill is provided with.
In multiplexed signals the multiplexing sequence identification of a plurality of headers all not simultaneously, power board is gone here and there to the multiplexed signals of receiving and the process changed specifically comprises:
By designated length multiplexed signals is gone here and there and be converted in the middle of parallel data, designated length equals the length of header of cell to be sent and the multiplexing number purpose product of multiplexed signals; According to the multiplexing sequence identification that prestores, judge any header that whether comprises in this centre parallel data in described a plurality of header, and the position of the header that is comprised in parallel data is identical with the position of this header in described a plurality of headers; If, then multiplexed signals not being shifted, the middle parallel data that promptly obtains is position parallel data accurately; Otherwise, according to default direction multiplexed signals whenever being moved a bit once goes here and there and changes, in the parallel data that obtains, comprise any header in described a plurality of header, and till the position of this header in parallel data was identical with the position of this header in described a plurality of headers, the parallel data that then obtains was a position parallel data accurately.
For example, comprise 4 headers in the multiplexed signals, their value is respectively A, B, C and D; The value that data are arranged in judging parallel data is that " B " and this data are the 2nd data in the parallel data, and then the parallel data that obtains this moment is a position parallel data accurately, need not be shifted again.
In multiplexed signals the multiplexing sequence identification homogeneous phase of a plurality of headers simultaneously, power board is gone here and there to the multiplexed signals of receiving and the process changed specifically comprises:
By designated length multiplexed signals is gone here and there and be converted in the middle of parallel data, designated length equals the length of header of cell to be sent and the multiplexing number purpose product of multiplexed signals; According to the multiplexing sequence identification that prestores, judge whether this centre parallel data is identical with described a plurality of headers; If, then multiplexed signals not being shifted, the middle parallel data that promptly obtains is position parallel data accurately; Otherwise, according to default direction multiplexed signals is whenever moved a bit and once go here and there and change, till the parallel data that obtains was identical with described a plurality of headers, the parallel data that then obtains was a position parallel data accurately.
For example, comprise 2 headers in the multiplexed signals, their value is 6; When the value of two data in judging parallel data is 6, then obtain position parallel data accurately.
Wherein, the power board string and change the direction of time displacement can be for moving forward, also can be for moving backward, be shifted according to identical direction in the process of displacement as long as guarantee, if cell length to be sent is N byte, corresponding transmission time periods is T, then in the time of multiplexing number * T, mode by displacement can obtain position parallel data accurately.
For example, referring to Fig. 4, the length L of cell is 1 byte in the cell to be sent, and multiplexing number is 4, and the header in the multiplexed signals of 12.5Gb/s is respectively H
1, H
2, H
3And H
4This multiplexed signals is gone here and there and changed, then parallel data has 4 * L=4 byte, totally 32 bits, if a transmission time periods of the length N byte correspondence of cell to be sent is T, then in the time of multiplexing number 4 * T, the middle parallel data of going here and there first and be converted to is detected, judge whether to comprise in this centre parallel data a plurality of header H that prestore
1, H
2, H
3And H
4In any header, and the position of the header that is comprised in this centre parallel data is identical with the position of this header in described a plurality of headers, if, then multiplexed signals not being shifted, this centre parallel data is position parallel data accurately; Otherwise, multiplexed signals is carried out to backward shift, whenever move a bit backward, all once go here and there and change, and detect in real time, comprise any header in described a plurality of header in the parallel data that after detecting displacement, obtains, and the position of the header that is comprised in this parallel data is identical with the position of this header in described a plurality of headers, then this parallel data is a position parallel data accurately, exports corresponding parallel data and exchanges to crosspoint.
Step 105: power board exchanges respectively and exports parallel data, finishes then.
It is that example describes that said method carries out the multiplexing high speed signal that obtains with ply-yarn drill to low speed signal, and this ply-yarn drill is the low speed bus ply-yarn drill.In actual applications, PSE can use low speed bus ply-yarn drill and high-speed bus ply-yarn drill simultaneously, promptly in a PSE, the ply-yarn drill that has can carry out multiplexing to sent cell, the ply-yarn drill that has can not carry out multiplexing, and carrying out the multiplexing number of multiplexing ply-yarn drill also can be different.For example, referring to Fig. 5, power board is received the multiplexed signals of 3 signal: 12.5Gb/s that 3 ply-yarn drills are sent, the multiplexed signals of 6.25Gb/s, 3.125Gb/s not multiplexing signal, go here and there according to the mode of above-mentioned displacement control string and conversion and change by string and converting unit, promptly the multiplexed signals of 12.5Gb/s is converted to the parallel data of 4 3.125Gb/s, gives crosspoint 1,2,3 and 4 respectively and exchange, then output at interface 1 place; The multiplexed signals of 6.25Gb/s is converted to the parallel data of 2 3.125Gb/s at interface 2 places, gives crosspoint 1 and 2 respectively and exchange, then output; Give crosspoint 1 at directly that 3.125Gb/s is the not multiplexing signal in interface 3 places and exchange, then output.Wherein, because the length of cell to be sent all is isometric, corresponding, the transmission cycle of each cell is also fixed, and after crosspoint is received parallel data, when the cycle of current cell arrives, this cell is exchanged.
Present embodiment is gone here and there to the multiplexed signals of receiving in the mode of displacement according to multiplexing sequence identification and is changed, obtain position parallel data accurately, realized docking of low speed bus ply-yarn drill and high-speed bus power board, improved the compatibility of ply-yarn drill and power board, make and existingly can be applicable in the system of higher rate bus than low rate bus ply-yarn drill, effectively utilize existing resources, saved the cost of subsequent development.
